libstdc++.dylib created for llvm-gcc4.2-2.3 front-end?

Hi,

I’m trying to build from source the llvm-gcc4.2-2.3 front end.

My host OS is Ubunut 8.04. “make install” completed sucessfully, but I do not see a file called libstdc++.dylib in the pwd/…/install/lib/libstdc++.dylib area. In fact, I can’t find any file with an extension .dylib.

Have I done something wrong or is this a known issue with a workaround?

tia,
Bernardo
